ABSTRACT Objective: to discuss in the scientific literature strategies used prevent hypothermia newborns undergoing surgical procedures. Methods this is an integrative review, with structured search April and May 2020 08 databases, using descriptors: Hypothermia; Surgical Procedures, Operative; Infant, Newborn; Protocols. Four primary studies were selected analyzed three instruments assess meth...

A non-lethal, hypoxic conditioning stimulus has been shown by Rising and D'Alecy to increase hypoxic survival time in mice. To determine if endogenous opioids alter the hypoxic conditioning-induced increase in hypoxic survival time, we administered naloxone (0.1, 1.0 mg/kg i.p.) or saline (0.3 ml i.p.) 5 min prior to conditioning. Sixty percent of the mice received the hypoxic conditioning stim...

The comfort factor of a room is determined according to the location, characteristics and activities in room. In order for feel comfortable, tool needed cool hall Campus III UM West Sumatra as place academic measuring 28.3 m long, 8.3 wide, 3.2 high with capacity 130 people, requires air conditioning needs This study aims determine need cooling load space. research carried out literature review...

The main objective of this study is to predict air temperature and humidity at the outlet of a wire-on-tube type heat exchanger using neural networks. For this purpose, initially the heat exchanger was coupled to a refrigeration unit and placed in a wind tunnel. Afterwards, its performance was tested under various experimental conditions. We measured nine input parameters, namely, temperature a...

When growing various crops in greenhouses an important condition for obtaining high yields is compliance with the required parameters of temperature regime air environment. The conditioning systems currently used V generation “Ultra Clima” are equipped adiabatic panels that cool entering room by evaporation moisture from their surface. However, some cases, such not able to support values. This ...

The paper presents the neuro-fuzzy controller algorithm for air conditioning system. Neuro-fuzzy control combines the learning capabilities of neural networks and control capabilities of fuzzy logic control. The neurofuzzy controller for air conditioning system takes two inputs from temperature and humidity sensors and controls the compressor speed. The experimental results of the developed sys...

In order to meet the needs of humanistic education, museum buildings have developed vigorously in recent years. The protection and display cultural relics is an effective way continue historical information, which has important social significance. During design operation building air conditioning system, both thermal humidity environment exhibition room should be responsible for safety display...

Presented is the material and gas sensing properties of graphene-like nano-sheets deposited on 36° YX lithium tantalate (LiTaO3) surface acoustic wave (SAW) transducers. The graphene-like nano-sheets were characterized via scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The graphenelike nano-sheet/SAW sensors were exposed to differen...

The objective of this study is to present the test results of variable air volume (VAV) air conditioning system optimized by two objective genetic algorithm (GA). The objective functions are energy savings and thermal comfort. The optimal set points for fuzzy logic controller (FLC) are the supply air temperature (Ts), the supply duct static pressure (Ps), the chilled water temperature (Tw), and...
